In my experience it’s easy to find valve seating issues with a can of carb cleaner. I spray it in the intake and exhaust ports and look for leaks around the valves. I staked a loose valve seat in on my push mower about 10 years ago and It still runs fine.
You could press a new valve guide into the head, or just get a new or good used head, and put it all back together! I would guess that the valve lash required adjustment which allowed the head to overheat and metal expansion caused the guide to slip instead of just burning the valve face. You could try just pressing it back into position with a C clamp and a couple of small blocks of wood on each end, lapping the valves into their seats, and putting it all back together with a proper valve adjustment and you might never have anymore trouble with it again. Since you tore it down to the bottom end, you’ll need a new sump gasket, too. Don’t just use gasket maker; the thickness of the sump gasket gives the crankshaft it’s proper end play. New mowers are too expensive to replace over an issue this small, plus the new ones are all ultra cost cutter junk these days; better to fix than switch if you can do the work yourself! You’ll likely get more use out of fixing your old Murray than if you bought a new one with the cheap Chinese made engines most of them have now!
You may be spot on. The amount of slop in the rockers seemed excessive for sure. I think I may just give it a shot and see if I can put it back together and run it a few more years!
I had an e-series engine with 10 hours on it drop an exhaust valve seat, aka no compression. Briggs warranteed it. ruclips.net/video/V_CCmf_UXwU/видео.html go to 03:02 to see the seat.

If you can’t fix this motor, we had good luck with a harbor freight replacement engine,

How do you work with the gloves ?
It would drive me crazy, but I’m in Texas so it not terrible cold 😢
I usually end up losing them at some point, especially if I have to handle small things.
I’ve been waiting to try a Honda valve steam on a bs engine and see if it will hold value guide in place
Maybe this summer I can check it out 😮
I think I am going to see if I can get this guide pushed back in and get this one running again. Hopefully it will stay in!
Torque the head bolts this is why it's leaking oil
Rings on the E series are junk period
They don’t last very long and have to be replaced or junked 😢😢😢
To be fair, ten years of full season grass cutting, I think it did pretty good!
